CHAPTER 1 INTORDUCTION
Product Introduction
EH-500, EH-800A and EH-1600 is a standard Ethernet
concentrator that re-times and re-transmits the signal to each
network station on the LAN. It simplifies the implementation of
twisted-pair Ethernet compatible networks following the IEEE
802.3 10Base-2/5/T CSMA/CD standard. Each Hub has 5/8/16
modular RJ-45 STP ports and one BNC port; EH-1600 also have
an AUI port for attaching network devices (file server, bridge,
and workstations) or additional concentrators.
Product Features
EH-500/EH-800A/EH-1600 provides all the functions necessary
to support the requirements of Ethernet networks. These function
includes the following features:
♦5/8/16-port STP RJ-45 connector and one port BNC, one port
AUI(EH-1600).
♦Manchester decoder for clock and data recovery
♦Automatic preamble regeneration to compensate for any bit
loss
♦Lockup and auto-partition for jabber to isolate network
failures
♦Auto-Polarity correction
♦LEDs for Power, Collision, and Link, TX/RX per port
♦Desktop or wall-mountable(EH-500/EH-800A).

CHAPTER 2 GENERAL DESCRIPTION
Cover Panel of EH-500/EH-800A/EH-1600
On the cover panel, there are Power, Collision LED. And one
LEDs for each RJ-45 STP & BNC, AUI port (EH-1600);. These
LED indicators help in diagnosing line troubles and indicate the
status of data transmission.

Note: Use of both “DAISY-CHAIN”port and STP1 of EH-1600, STP8
of EH-800A or STP4 of EH-500 will make these two ports
malfunction.

There are one DC power connector, one BNC connector for the
hub, and one AUI connector for EH-1600.
Note: Pleases check the AC adapter bundled with this hub. The
DC output should be 5V~7.5VDC (EH-500) 7.5VDC
(EH-800A) or 12VDC (EH-1600). And it polarity should
